Burning Man 2011, Black Rock Desert, Nevada, United States

In 2007 Burning Man's "Green Man" theme received criticism for Crude Awakening, the 99-foot oil derrick that consumed 900 gallons of jet fuel and 2,000 gallons of liquid propane to blast a mushroom cloud 300 feet high into the sky.
In an attempt to offset some of the event's carbon footprint, 30- and 50-kilowatt solar arrays were constructed in 2007 as permanent artifacts, providing an estimated annual carbon offset of 559 tons.
On-site photography restrictions
Despite presenting itself as an event promoting self-expression, the terms of the Burning Man ticket require that participants wishing to use video-recording equipment (including, in practice, most digital cameras) sign over copyright in their images to Black Rock City, and forbid them from using their images for anything other than personal and private use. This has been criticized by many, including the Electronic Frontier Foundation.
